Wiper with vanes for use with viscous cosmetics
First Claim
1. A wiper for use in a cosmetics container having a bottle with a neck and an applicator rod and applicator, the wiper removing excess cosmetics from the applicator rod and applicator as they are withdrawn through the neck of the container, the wiper comprising:
- A) a wiper diaphragm adapted for mounting at the lower end of the neck of the bottle of a cosmetics container, the wiper diaphragm defining a wiper orifice and including a conical lower surface extending outwardly from the wiper orifice to an outer periphery of the wiper and descending from the outer periphery of the wiper to the wiper orifice;
B) a plurality of spaced-apart vanes extending downwardly from the lower surface of the wiper diaphragm and angularly outwardly from the wiper orifice; and
C) a plurality of flow channels defined between adjacent spaced-apart vanes and the lower surface of the wiper diaphragm for carrying wiped excess cosmetics away from the wiper orifice.

Abstract
A cosmetics container includes a bottle defining a chamber for containing cosmetics, the bottle including a threaded neck, and a cap removably secured to the neck. The cap has an applicator rod for extending through the neck into the cosmetics chamber and applicator at the distal end of the rod for carrying cosmetics. A wiper has i) a sleeve mounted in the bottle neck, the sleeve defining an outlet through the neck from the cosmetics chamber, and ii) a conical wiper diaphragm extending from the sleeve across the outlet and descending into the cosmetics chamber below the neck. The conical wiper diaphragm defines a central wiper orifice for accommodating passage of the applicator rod and applicator and for wiping excess cosmetics therefrom as the applicator rod and applicator are withdrawn from the cosmetics chamber. A plurality of substantially evenly spaced-apart vanes extend downwardly from the lower surface of the wiper diaphragm to below the wiper orifice, each vane having a leading edge and a trailing edge, the leading edge of each vane joined with the lower surface of the wiper diaphragm adjacent the wiper orifice, and each vane extending angularly outwardly from the wiper orifice to its trailing edge. Adjacent vanes define a flow channel therebetween for conveying wiped excess cosmetics outwardly from the wiper orifice and for mixing cosmetics, the plurality of vanes defining a plurality of such flow channels. A second, more flexible finishing wiper is provided within the first wiper.

15. A cosmetics container assembly for use in applying cosmetics, the cosmetics container comprising:
-
A) a bottle defining a chamber for containing cosmetics, the bottle including a threaded neck; B) a cap removably secured to the neck, the cap having an applicator rod for extending through the neck into the cosmetics chamber and applicator at the distal end of the rod for carrying cosmetics from the cosmetics chamber upon removal of the cap, applicator rod and applicator from the bottle; C) a first wiper having i) a first sleeve mounted in the bottle neck, the sleeve defining an outlet through the neck from the cosmetics chamber, ii) a conical wiper diaphragm extending from the sleeve across the outlet and having a conical lower surface descending into the cosmetics chamber below the neck, the conical wiper diaphragm defining a central wiper orifice for accommodating passage of the applicator rod and applicator and for wiping excess cosmetics therefrom as the applicator rod and applicator are withdrawn from the cosmetics chamber, iii) a plurality of substantially evenly spaced-apart vanes extending downwardly from the lower surface of the wiper diaphragm to below the wiper orifice, each vane having a leading edge and a trailing edge, the leading edge of each vane joined with the lower surface of the wiper diaphragm adjacent the wiper orifice, and each vane extending angularly outwardly from the wiper orifice to its trailing edge, and iv) adjacent vanes and the lower surface of the wiper diaphragm defining a flow channel therebetween for conveying wiped excess cosmetics outwardly from the wiper orifice, the plurality of vanes defining a plurality of said flow channels. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
